So just think about this. Each season there are 3 new armor exotics released.This means that sooner or later we will run out of vault space from exotics alone. Recently there is a new element for armor, stasis. This leads to some difficult situations like: should my sunbracers be arc because melee mods are arc, or should it be stasis so I can run melee kickstart? Compound this with the fact that each raid has its own armor set with a unique mod slot and once again there are four elements for each armor piece. It should be clear that there is not enough vault space for the game now and much less so to accommodate its future growth. To solve some of this issues I've seen suggestions like being able to masterwork armor on multiple elements at the same time. This would alleviate some of the problem but what we really need is to be able to pull our armor rolls from collections or some long term solution to combat the growth in the number of exotic armor. This is without even getting in to the guns. Oh my, so much to say about the guns and vault space. I wont go into this to keep this post somewhat brief. But the point here is that this issue is so bad it is not a quality of life thing anymore, it is directly affecting players ability to make builds and incentive for loot, as decreased vault-space means more tradeoffs must be made and only a select few items are worth going after.
